The invention relates to novel medical equipment for scar repair. An elastic ring is arranged in a position of a sleeve opening of an anti-seeping sleeve; a clamp groove used for installing the elastic ring is formed in the outer side wall surface of a strip body; and a groove opening of the clamp groove points at the inclined upper side. The medical equipment provided by the technical scheme has the advantages that a strip body generating plastic deformation can be folded to be consistent with the physiological curve of each affected part of the human body; then, repair liquid and rehabilitation liquid are coated on a medicine anti-seeping layer; the medical equipment is fast pasted to the scar part or the skin to be nursed, so that the treatment on the large-area affected part can be realized. In addition, the medicine anti-seeping layer formed by polyethylene or polyvinylidene chloride materials cannot absorb active ingredients, so that the coating quantity of the repair liquid and the rehabilitation liquid can be effectively reduced, and the volatilization and the decomposition of the active ingredients can be relieved.

The invention discloses anti-aging equipment and method for a batch-type asphalt mixing tower. The equipment comprises a blender whose inner top face is equipped with an oxygen content monitoring device and a gas pressure monitoring device. The bender is further connected with a material weighing machine, an asphalt weighing machine, an inert gas storing device, an inert gas recycling device and a gas-discharging pressure-reducing device. Inert gases such as nitrogen and carbon dioxide are sent into the sealed blender, so that the contact opportunity of asphalt and oxygen can be reduced, and the aims of increasing the internal gas pressure in the blender and reducing volatilization of light oil are achieved. The higher blending temperature and the longer blending time are achieved, so that mineral aggregate wrapping degree of the asphalt and the blending uniformity can be improved. The oxygen content and the gas pressure in the blender can be monitored, so that the filling amount of the inert gases can be reasonably controlled. An oxygen removing device in the inert gas recycling device can utilize fuel combustion in the device to remove oxygen and the inert gases recycled after the oxygen removing process are conveyed to the inert gas storing device through a pipeline.
